Extreme sky diver Felix Baumgartner has announced his intention to jump through the sound barrier. Plans call for him to jump from a balloon at an altitude of 39 kilometers. This will break the altitude record set by US Air Force colonel Joe Kittinger in 1960.
Baumgartner is best known for being the first person to fly across the English Channel with a carbon wing in 2003.
